SAFETY REMOVABLE FASTENER Application filed March 19, 1982. Serial No.599,889.

This application is an improvement on my application Serial No. 578,268and now Patent Number 1,856,843, filed on December 1st, 1931 andentitled Safety removable hook fastener slide This invention relatesparticularly to new and useful improvements in a safety hook fastener.

. The invention has for an object the conostruction of a safetyhookfastener which is characterized bythe provision of a control slideequipped with a handle piece adapted to assume a latched inoperativeposition.

The invention has for a still further object the arrangement of meansupon the handle adapted to frictionally engage portions of the controlslide for accomplishing holding of the handle in the inoperativeposition. I The invention has for another object the arrangement ofcoacting means on the handle and the slide so that the parts may assumean inoperative position without resorting to friction.

Particularly, it is proposed to provide a re- 26 silient construction toresiliently hold the handle in the inoperative position.

Furthermore, it is contemplated to arrange theresilient structure in amanner so that the removal of the handle is possible whenever desired.

The invention has for a still further object the construction of adevicev of the class described which is of simple, durableconstruc tion,dependable in use and efficient in action,

and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention aremore particularly set forth.v

In" the accompanying drawing forming a material part of this invention:

1 is a plan view of a device constructed according to this invention.

Fig. 2 is a side elevational View of Fig. 1.

Fig. 3 is a bottom elevational view.

Fig. 4 is a View similar to Fig. 1 but illustrating a modifiedarrangement.

Fig. 5 is a side elevational view of Fig. 4.

Fig. 6 is a bottom elevational view of Fig. 4.

Fig. 7 is a sectional view taken on the line 77 of Fig. 5.

The safety hook, according to this invention, comprises upper and lowerspaced trapezoidal guide plates 10 and 11 respectively having theiredges 12 turned intowards each other. A separation post 13 issubstantially of triangular shape and interposed between the guideplates 10 and 11 at the latch ends thereof so as to form passagesadapted to engage and disengage the hooks of a hook fastening device. Arivet 14 engages through the guide plates 10 and 11 and the post 13 tohold the parts firmly together.

The guide post 13 projects slightly from the rear edge of thetrapezoidal plates and the plates at that area have small projections 15extending over the post as clearly shown on the drawing. The top guideplate 10 is provided with a strap 16 which extends from the front to therear. A handle 17 is formed with inturned directed prongs 18 engagingbeneath the strap 16 so that it may be drawn to any position along thestrap. Dot and dash lines 17 in Fig. 2 indicate a released position ofthe handle.

A pair of pegs 19 project from the handle 17 and are arranged so as toengage in the corners formed by the edges of the trapezoidal guide plateand the projection 15. This is clearly shown in Fig. 3. It iscontemplated that the frictional resistance between the projection andthe guide'plate will serveto hold the handle latched in this particularposition. Thus, the handle will not flap loose- 1y back and forth duringuse of the article upon which the fastener is engaged.

. In the modified form of the invention illustrated in Figs. 4.7inclusive, provision has been made to positively hold the handle in theinoperative position instead of depending upon friction. Moreparticularly, each of the pegs 19 are formed with notches 20 so thatthey simulate hooks and may engage upon "the edge of the trapezoidalplate 10. A spring 21 is secured upon the end of the 100 1 may slip pastso that the handle is completely removed. A stiff resilient spring 23 ismounted between the reduced end of the strap 16 and the spring 21 andserves normally to close the openings 22 through which the prongs 18 maypass. The arrangement allows the handle 17 to be pulled so that thespring 21 is flat against the spring 23 and in this position the pegs 19may have their notches receive the edge of the plate 10. If it isdesired to remove the handle 17 it is merely necessary to pull quitestrongly upon the handle so that the spring 23 also bends whereupon thehandle comes out.

In operation the control slide is engaged upon rows of hook fastenersand is adapted to lock and unlock the hooks thereof as it is moved inone position or the other. When the control slide is not used the handleshould be latched so that it does not move around freely.

.While I have shown and described the preferred embodiment of myinvention, it is to be understood that l do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is 1. A safety hook fastener,comprising upper and lower spaced trapezoidal guide plates, a separationpost between said guide plates rigidly connected therewith, a strapacross the top guide plate, a handle with prongs extending beneathopposite edges of the strap, pegs projecting from said handle andpositioned thereon to engage against one edge of one of the guide platesto hold the handle against free moving, and a resilient elementinterposed between one end of said strap and prongs to force the pegsagainst the edge of said guide plate.

2. A safety hook fastener, comprising upper and lower spaced trapezoidalguide plates, a separation post between said guide plates rigidlyconnected therewith, a strap across the top guide plate, a handle withprongs extending beneath opposite edges of the strap, pegs projectingfrom said handle and positioned thereon to engage against one edge ofone of the guide plates to hold the handle rea ies against free moving,said strap formed with cut outs and which ordinarily allow the prongs toslip past, and a flat spring mounted on the strap and across the cutouts for normally holding the prongs within the boundaries of the strap.
